None of the 19 Texas stores set to be sold is in San Antonio. Twelve of the stores are in El Paso, three in Corpus Christi and one each in Austin, Kenedy, Del Valle and Mathis.

Empire also will have the option of buying an additional location in Georgia owned by Couche-Tard, the FTC said. The store was damaged by a tornado earlier this year.

The 70 stores represent about 6 percent of the 1,178 U.S. stores that Couche-Tard is acquiring from CST. Couche-Tard operates almost 4,700 convenience stores in the U.S., primarily under the names Circle K and Kangaroo Express. Overall, Couche-Tard has about 12,500 stores.

CST also has about 885 retail locations in Canada, according to a Securities and Exchange Commission filing last month. Of those locations, 571 only sell fuel while the remainder sell fuel and merchandise. Couche-Tard said it expects to obtain regulatory clearance for the deal from the Canadian Competition Bureau later this week.

Couche-Tard previously has said it would sell off some of CST’s Canadian operations to Calgary-based Parkland Fuel Corp. for $750 million after the CST purchase closes.

CST shareholders will receive $48.53 in cash per share under terms of the Couche-Tard purchase. CST’s shares rose 18 cents Monday to close at an all-time high of $48.54.

According to an FTC complaint, Couche-Tard’s acquisition of CST would have created a monopoly in 10 U.S. markets without the divestitures. The deal also would have reduced the number of independent operators in the 61 other U.S. markets and resulted in a “highly concentrated market” in all 71 markets.

The sale of the CST stores to Empire is expected to close in August or early September, Couche-Tard said.

CST was spun off from Valero Energy Corp.’s retail operations in 2013 and instantly became San Antonio’s third-largest public company based on revenue.

An aggressive expansion strategy saddled CST with billions in debt and led some restless shareholders to complain about its lackluster performance and to ask whether it should be put up for sale. Finally, in March 2016, CST succumbed to the pressure and agreed to pursue “strategic alternatives,” including a potential sale. The shares were trading at $34.21 at the time of the announcement.

In May of last year, CST agreed to sell some of its stores in California and Wyoming to 7-Eleven for $408 million. Then, in June 2016, reports had two of the largest convenience store operators — Couche-Tard and Seven & I Holdings, the foreign owners of 7-Eleven — bidding to acquire CST.

CST’s shares surged in August after the Wall Street Journal reported that Couche-Tard was the likely winning bidder for the chain. Less than a week later, the deal was confirmed. But the offer price of $48.53 a share was well below the sum that some believed CST would fetch. Wells Fargo Securities, for example, had said any takeout offer would at least be above $50 a share, with the potential for bids as high as $56.

Couche-Tard anticipates the purchase will boost its earnings per share by up to 50 cents and yield up to $200 million in pretax cost savings within three years, according to a presentation posted on its website last summer.

Once the CST deal is completed, Couche-Tard will control the general partner of CST subsidiary CrossAmerica Partners, which distributes fuel to about 1,200 U.S. locations. Couche-Tard also will own 100 percent of CrossAmerica’s incentive distribution rights and about 21 percent of its outstanding common units.

The sale of CST will mark the second time in the span of about eight months that a San Antonio mid-cap company — defined as a company with a market value between $2 billion and $10 billion — has changed hands. In November, cloud computing company Rackspace Hosting Inc. was acquired by New York private equity firm Apollo Global Management for $4.3 billion.
